Split tee device

ABSTRACT

This invention relates to a two-piece removable split-tee device adapted to removably hold a rod disposed transversely to a pair of parallel rods as in a jungle gym or a store display fixture. The device comprises two substantially mirror image half pieces slidably disposed along a fixed rod and adapted to secure a second rod at a right angle thereto. Hook means are provided in the two half pieces to produce a co-acting locking engagement therebetween.

2 Claims, 8 Drawing Figures SPLIT TEE DEVICE The conventional plumbers type display T-fitting is of integral construction and can not be easily removed from the ends of a fixture having fixed ornamental balls on the ends thereof.

As a statement of this invention, the invention consists of the provision of split T-shaped removable holders for ladder rungs, so that the rungs may be selectively disposed and selectively spaced upon the parallel longitudinal ladder supports.

An objective of this invention is to provide rung supporting means for rapidly adding, subtracting or spacing ladder rungs.

Another objective is to provide a two-piece lockable T-shaped holder adapted to be selectively mounted on a ladder support to hold a rung thereto.

These and other objectives of this invention will become apparent when reading the following disclosure of an illustrative embodiment shown in the accompanying drawing in which;

FIG. 1 is a perspective view of a rung selectively secured to a pair of removable split T-shaped holders of this invention securing a rung to a pair of parallel supports,

FIG. 2 is an end view ofa split T-shaped holder,

FIG. 3 is a side view of said T-shaped holder,

FIG. 4 is a front view of said holder for receiving a rung,

FIG. 5 is a section view taken on line 5-5 of FIG. 6 of the seperated split T-shaped holder, showing the fixed hook means of one half section in relationship to the pin for engaging said hook disposed in the co-acting half section,

FIG. 6 is a section view taken on line 6-6 of FIG. 5 and showing the manner of securing the hook within a cavity by means ofa rivet pin in one section and the location of the locking pin for engaging said hook in a cavity of the other section of the holder,

FIG. 7 is a view taken along the split face and on line 7-7 of FIG. 1 and showing the cavities for receiving rubber pads to effect rigid seizure of said holder to said ladder rung and support, and

FIG. 8 is a section view taken on line 88 of FIG. 7 showing the depth of the seizure rubber receiving cavities.

This invention consists of two preferably metal half sections each having a T-shaped configuration. The half section 10 has a hook 10X and the half section 11 is provided with a co-acting locking pin 11X for said hook. Otherwise the two half sections are substantially mirror images and can be made in a single mold since the cavities for both the hook and its co-acting locking pin in the respective sections are substantially alike.

As shown in FIG. 1 a ladder rung 12 is movably and removably selectively secured to a pair of opposed ladder supports 13. For display type ladders mounted at right angles to a store wall, the ends of the supports are provided with ornamental fixed balls 14.

As shown in FIG. 3, the half sections are each provided with a central substantially hemi-spherical dome 20 integral to a pair of opposed ladder support embracing extensions 21 and integral also with a rung embracing extension 22.

The cavity of the hook holding section is provided with a hook holder rivet pin 23 holding said hook 10X in place. The corresponding cavity molded in the coactmg holder half section, is provided with a suitably located locking pin 11X so that the hook 10X may be inserted into said cavity along side said pin 11X and thereafter moved into hook locking engagement with said pin 1 1X.

The holder sections may be made of plastic if desired. When made of metal, preferably the sections 21 are each provided with a plurality of rectangular cavities 24 in said extensions 21 and 22 for receiving relatively thin rubber pads 25 to frictionally size the ladder support 13.

Additionally, the extensions 22 may be provided with apertures for set screws or locking pins, if desired.

Iclaim:

l. A T-shaped two piece holder adapted to secure a rung to a pair of opposed ladder supports comprising a pair of substantially alike T-shaped half sections adapted to embrace a support and a rung; and hook and pin locking means disposed respectively in said half sections to effect locking engagement therebetween and to said ladder support and rung; the T-s haped half sections are each provided with a cavity in the wall portion opposed to a rung embracing portion of said half section and a hook fixedly secured within one cavity and a co-acting locking pin secured within the co-acting cavity of a co-acting half section.

2. The holder of claim 1 wherein the portions of the half-section embracing the ladder support are provided with suitable cavities adapted to receive rubber friction pads to effect seizure of said half sections to said ladder supports. 

1. A T-shaped two piece holder adapted to secure a rung to a pair of opposed ladder supports comprising a pair of substantially alike T-shaped half sections adapted to embrace a support and a rung; and hook and pin locking means disposed respectively in said half sections to effect locking engagement therebetween and to said ladder support and rung; the T-shaped half sections are each provided with a cavity in the wall portion opposed to a rung embracing portion of said half section and a hook fixedly secured within one cavity and a co-acting locking pin secured within the co-acting cavity of a co-acting half section.
 2. The holder of claim 1 wherein the portions of the half-section embracing the ladder support are provided with suitable cavities adapted to receive rubber friction pads to effect seizure of said half sections to said ladder supports.
